The Differences between the 90-day and 120-day License Thresholds in Windows 2003 Terminal Services

In Terminal Server environments running on Windows 2003 servers, there are two different licensing thresholds: 90-days and 120-days. Here are the differences between the two: The 90 Day Threshold If a Terminal Server requests a Terminal Services CAL (TS CAL) from a license server that does not have any activated TS CALs, the license server will distribute a temporary TS CAL that is valid for 90 days.

In Terminal Server environments running on Windows 2003 servers, there are two different licensing thresholds: 90-days and 120-days. Here are the differences between the two:

The 90 Day Threshold
If a Terminal Server requests a Terminal Services CAL (TS CAL) from a license server that does not have any activated TS CALs, the license server will distribute a temporary TS CAL that is valid for 90 days. This is a change from Windows 2000. In Windows 2000, only activated license servers could distribute temporary TS CALs. In Windows 2003, non-activated license servers can also distribute TS CALs.

The 120 Day Threshold
If a Terminal Server cannot locate a license server, the Terminal Server will still allow client devices to connect and run sessions for 120 days. In this case, the Terminal Server does not provide a temporary TS CAL. (After all, only license servers can provide the CALs that Terminal Servers distribute to clients.) This limit was 90 days on Windows 2000-based Terminal Servers.

In your explantion, does it mean I can have 210 days of "free evaluation" for 2003 terminal server: meaning I dont install licensing server until the 90th day, and I dont activate the licensing server until the 210th day.

TS 2003 will work for 120 days without a license server. So you install the license server on day 120, and it will hand out 90-day temps that would be valid through day 210. Of course you still have to be in compliance with the licensing tems though, even during this period.
